Asphalt shingles can be divided into three types according to the basic source material, namely road asphalt, oxidized asphalt, and modified asphalt.
Road asphalt has low melting point, heavy oil content, easy to volatilize, low price, and good viscosity. It is mostly used for asphalt road configuration. Oxidized asphalt is also called No. 10 asphalt. It has good temperature resistance and is not easy to volatilize. It is also called solid asphalt and has good aging resistance. , The use time is long, and the modified asphalt is mostly used for waterproofing membranes.
Asphalt tiles, also known as colored asphalt tiles, are directly crushed from natural colored sand or natural rocks and processed by adding asphalt raw materials. The color is natural, compact, permanent color retention, and beautiful in color.
The laying of asphalt tiles must be laid in sequence. Along the gable side and cornice, ensure that the edge of the first layer of asphalt tiles is aligned with the edge of the initial layer of asphalt tiles. The laying of asphalt tiles must be precise, but there should be no squeeze between tiles. The laying of the first layer is the key. During the laying process, it is necessary to constantly check whether the asphalt shingles are aligned with the required horizontal line. The side of the first asphalt shingle on the second floor should be staggered by half an inch from the side of the previous layer of asphalt shingles. leaf. Then lay them in sequence. The first sheet of the three-layer asphalt tile should cut off the entire blade so that it is staggered from the first sheet of the second layer of asphalt tiles, and the bottom edge of the asphalt tile should be at the top of the decorative seam of the second layer of asphalt tiles. Look flush.
