Asphalt shingles can be divided into three types according to the basic source and basic materials, namely trailing asphalt, oxidized asphalt, and modified asphalt. Pathway asphalt has low melting point, heavy oil content, easy volatility, low cost 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 volatile. It is also called solid asphalt and has good aging resistance , The utilization time is long, and the modified asphalt is mostly used for waterproofing membranes.
Asphalt shingles, also known as colored asphalt shingles, are directly crushed by natural colored sand or natural rocks, and processed with asphalt materials. The color is natural, close, permanent and beautiful.
The laying of asphalt shingles must be laid in order. Along the edge of the gable and the cornice, it is necessary to ensure that the first layer of asphalt shingles is aligned with the edge of the initial layer of asphalt shingles. Pressure, 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. leaf.
Next, lay them in sequence. The first sheet of the three-layer asphalt shingle should be cut to lose the entire blade, so that it is staggered from the first sheet of the second layer of asphalt shingles, and the bottom edge of the asphalt shingle should be the same as the top of the decorative joint of the second layer of asphalt shingles. Measure evenly.
