There are various types of mixtures of asphalt paving of materials. The type and the quality of asphalt cement and the size of the aggregate (rocks) explain the differences. The smaller the aggregate is, the more the finished product will be weak. The majority of the people want a surface finished very smooth. This requires mixture to have a smaller aggregate. If is this what you want, your fitter can have to install two layers to pave the material. The first layer will be slightly thicker and will have rocks slightly larger. The top coat will be thinner (1/4 inch 1 to 1) and will have smaller stones and rough sand. You always ensure that a tack coat of asphalt is used between the layers. This acts as an adhesive with the obligation the layers together. A tack coat is not necessary if the second layer is applied little time after the first layer. If you repaving an existing alley, take guard of the cracks of reflexion!

The cracks of reflexion are cracks which develop in the new pavement directly above the existing cracks in the old pavement. It is a major problem if you install asphalt paving the concrete of surplus. Last technology suggests that a few days after asphalt is installed, you should consider slits of cutting of saw in new asphalt directly above the existing cracks. These sawcuts will be right and can be filled of flexible scellor of slit.

If repaving, you ensure absolutely that all dust and dirtiness are removed from the old surface. Remove all the vegetation of the cracks and edge of the alley as well. Be sure to fill all the low spots with equipment of connection before applying the top coat of asphalt.

Sealing And Maintenance

Much of associations recommend that you seal your new driveway one year after it is installed. Be sure to employ a commercial bituminous scellor of emulsion of the water of high quality. If your order is on a hill, consider to employ a scellor who contains sand.

Do not seal your alley each year! The scelleurs are coatings, just like painting. You can easily apply too much and the coatings will start to split and peel. Reseal only the alley after you can clearly see that the old scellor carries. When the color of the aggregate (rocks) starts to show, it is time to reseal. Since the scellor will carry to far more quickly in the sectors where there is traffic of foot and car, apply the scellor to the sectors of the not-traffic a little thinner. Otherwise, you will start to obtain a preparing of scellor who can start to split and peel.
