Asphalt – the Most Popular Building Material

Asphalt is a composite material which is mixed with mineral aggregates and used in various construction projects. In recent times it has become the obvious choice for paving driveways. Driveways made from the material are both cheap and at the same time long lasting. With proper maintenance a driveway or pavement can last for as long as twenty to thirty five years. Being both strong and flexible, asphalt driveways and pavements can be built in both hot as well as cold climates.

The material is very flexible and thus can be handled easily, giving it an advantage over other construction material in terms of handling stress and cracking. Preparing the ground for paving with asphalt is much easier depending on the condition of the soil. In some cases new pavements can be made directly over older pavement without any special preparation. The material is also weather and water resistant and remains unaffected by most chemicals too.

Although construction work with this material is pretty cheap, driveways and pavements made from it require proper maintenance. The most important aspect of maintenance is seal coating the asphalt properly and in proper time. When the pavement is made, you should not seal coat it for at least three to six months. The reason is that during this time the material undergoes a curing phase. In the curing phase it releases various chemicals. During that period when the surface is wet you will find that instead of being transparent, the water has a rainbow colored hue. It means that the water and the chemicals are still mixing.

After the curing phase is over it is time to seal coat your driveway. If the asphalt is not properly sealed it will oxidize and its color will fade from black to brown. When the material gets oxidized it losses its flexible properties leading to cracks. Without proper sealing, sunlight, water and other weather conditions will adversely affect your driveway. Seal coating also protects the surface from gasoline and oil. The asphalt binder, which holds the stone together, is a petroleum product. When it comes in contact with other petroleum products like oil and gasoline it bonds together with them. This deteriorates its binding capacity and the stones begin to fall off.

Sealing should be done every three to five years. It can be done by the driveway owner himself but it will take more time and effort. Hiring a professional firm will make the job much easier. The seal coating typically needs around three to five days to dry and during this time you cannot park anything on your driveway. A properly maintained drive way will last a long time.

In the field of construction materials, asphalt only faces competition from concrete. But according to various reports it is seen that concrete is more prone to cracking and buckling because of its more rigid nature. Paving with concrete is time consuming and at the same time costly repairs are needed more frequently. Along with other advantages the fact that asphalt paving comes at half the cost of concrete paving clearly makes the former the more popular construction material.

Sealcoating Equipment

What is sealcoating equipment? To answer this question, we must first look into reasons as to why sealcoating is necessary. It is a very common thing to see potholes on the streets. These potholes end up disrupting traffic and cause a lot of trouble for vehicles as well as pedestrians. Covering up these potholes with asphalt or coal tar is known as sealcoating. Sealcoating has become very necessary nowadays, because bad weather conditions prove to be very fatal for the roads, and ends up damaging them. Previously, sealcoating equipment would not be used, and the results were not good. The layers of asphalt would perish very easily. Sealcoating equipment is used mainly in infrared heating. Be it asphalt, or coal tar, they are used to apply them to the damaged pavements or roads. Sealers are a special type of equipment that is used to protect an older layering of asphalt from further deterioration caused by natural calamities like rain, storms and bad weather conditions. If water seeps in, then the layer will get ruined. This equipment is also used for new surfaces to lock the important aspects of asphalt, and prevent them from getting damaged.

Is sealcoating equipment available for one and all?

Yes, it is available for anyone who wants to use it. However, the difference lies in the size of the equipment and machinery. Mainly, sealcoating equipment was only available to people who wanted to take up sealing as a professional job. Contractors would mainly buy such equipment, due to the high cost. However, nowadays, this equipment is available to other people as well. Private home and business owners may want to fix their backyard when it gets damaged. For them, an easier version called the do-it-yourself squeegee, brooms and buckets are available. One thing professional contractors should do by using this equipment is to make their business highly profitable.

Choosing the best seacoating equipment

Selecting the best sealcoating equipment is not as easy as it sounds. First, you must figure out what work you will need it for. Depending on the quantity of work you want to do, you should select the appropriate size of equipment. The most important factor that should allow you to choose the best equipment is the profit you will be able to generate. You will have to look into more factors than one. The sealcoating equipment you choose will depend on factors such as the availability of raw materials, their quality, and the workmanship that is available to you. Another thing you must be sure of – how much work are you planning to do in a day. It is not always necessary that more the amount of work you plan, the more profit you will receive. There are overhead costs like employee salaries as well. Thus, choose a suitable amount of work to be done, and accordingly choose the sealcoating equipment that will help you speed it up. Think wisely and choose well!

There are many websites which sell sealcoting equipment. You will have to provide them your work plan, and they will suggest to you the most suitable equipment!

Complying With Energy Performance Standards

The European Union Directive 2002/91/EC with regards building energy performance, set an unprecedented step in curbing carbon dioxide emissions. These emissions cause environmental degradation with the introduction and implementation of the Energy Performance Certificates, which has been transposed into British law by The Energy Performance of Buildings, Certificates and Inspections (England and Wales) Regulations 2007 and the Housing Act 2004.

Following the thread of discussions and meetings – and pushing for a sustainable energy program, the European Union has been successful in this endeavour. The law mandates both residential and commercial buildings to comply with the directive on energy performance of buildings.

Types Of Buildings and Services

The home inspectors or domestic energy assessors – who have been certified by an approved accreditation scheme – produce the EPCs whether it is a residential or commercial EPC. For residential EPC, the assessor or inspector surveys and examines the property – based on some basic data such as domestic boiler, loft insulation, hot water tank, among others. These data are inputs for calculation of the energy efficiency of that building – by a software programme designed for the purpose. The use of a scale valued from A to G, with A as the most efficient and G the least – most UK residential owners and sellers are now aware of how to improve energy efficiency as recommended in their EPCs.

The commercial inspectors must be knowledgeable in the building spectrum – to be able to carry out survey and inspection accurately and come up with precise energy performance rating appropriate to the building level. Commercial buildings – whether on sale, rented or under construction, used in the conduct of trade and commerce or businesses – require the commercial EPC. The level of the building is based on the pre-determined categories – which the inspector use as basis for the production of commercial EPC. Level 3 are small buildings, with cooling systems less than 12kw and heating systems less than 100kw; level 4 are purpose-build buildings with cooling systems more than 12kw and heating systems more than 100kw; and level 5 are larger buildings of complex service and form.

Calculations of the Energy Performance Certificate energy ratings are based on the RDSAPv3 (Reduced Data Standard Assessment Procedure) derived from the UK Building Research Establishment’s Domestic Energy Model.

Where to Get an EPC

The business of obtaining an energy performance certificate has seen more and more private residential and commercial buildings owners, contractors and sellers – complying with the EU directive because of the ease and convenience in applying for a residential or commercial energy performance certificate.

Most of those who are into the EPC provision service have in their team qualified assessors who will conduct building survey and inspection. Apart from inspection, the assessors are also trained on SAP ratings, recommend schemes, designs and technologies for a rationalised and efficient energy use, provide training courses for the private sector on how to conduct energy assessment, and manage energy improvement modification processes.

Searching for an EPC provider can be done online. The sites provide quotes and Applications Form to give the client a hassle-free EPC.

Asphalt Repair

Due to erratic weather, the conditions of roads start to deteriorate. Due to rains or similar harsh weather, many potholes can be found on the roads. It is necessary to take immediate actions so that they can be fixed, otherwise they will end up disrupting traffic. The government has always taken care to fix the potholes, but the methods they would use previously would end up causing a lot disturbance because of the noise and the air pollution. Moreover, they would not have safe conditions for employees to work, the carbon content would be high, and the repairing done would be of a relatively low standard. These reasons gave way to asphalt repair using an infrared process. This process came into use because of the disadvantages of the old methods. Previously, the asphalt would be saw-cut. This means that the old asphalt would first be cut out, and then the gap would be filled by newly cut asphalt. The main reason why this method failed was because of the small gaps that would still be present. It is physically impossible to cut new asphalt in the exact same shape as the hole that needs to be covered. As a result, some small gaps would be left behind. Here, accumulation of water would start taking place, and would eventually end up ruining the new asphalt as well. However, with the new method of asphalt repair, all these problems do not occur.

What is infrared asphalt repair?

As the name suggests, this method involves an infrared process. Infrared is used to heat up the new asphalt so that it becomes soft, and is easier to work with. Then, this asphalt is added to the hole, so that they form a seamless layer. Due to this seamless layer, water is not able to penetrate, and the new patch stays on for a long period of time. Thus, infrared asphalt repair is very reliable, and does not perish easily.

Steps followed during infrared asphalt repair –

Step 1: First, the pothole, as well as the area around it should be cleaned. This is done to ensure that the coating of asphalt given results in a smooth layering.

Step 2: The device in which the infrared heating will take place is kept over the pothole for around 10 minutes. Care should be taken so that the asphalt is heated to give it a soft texture. This is done so that working with it becomes easy.

Step 3: After the heating is complete, the heated asphalt (currently at a temperature of approximately 350 degrees) is removed and raked. The raking is done so that the asphalt repair layer is smoothened out. It is necessary to make the patch very smooth, otherwise it will affect vehicles that will ply over them.

Step 4: Some rejuvenating oils are also used for a better finish, because most of them get evaporated when the heating of the asphalt takes place.

Step 5: Then, a roller is used to make the asphalt repair layer at a similar level as the road. After it is evened out, a buffer time of around 20 minutes is kept, depending on the size of the patch, before it can be used by pedestrians and vehicles.

This is how asphalt repair is done. The new infrared process is being used nowadays, as the job gets over faster and yields better results.
