A riparazione stradale è u mantenimentu di u mantenimentu di u mantellu di l'asfaltatu hè un materiale di riparazione efficiente è conveniente. A seguente hè una introduzione detallata:
1. Definition and composition/^/^Asphalt cold patching material, also known as cold patching material, cold patching asphalt mixture or cold mix asphalt material, is a patching material composed of matrix asphalt, isolation agent, special additives and aggregates (such as gravel). These materials are mixed according to a certain proportion in professional asphalt mixing equipment to make "asphalt cold replenishing fluid", and then mixed with aggregates to finally make finished materials./^/^2. Features and advantages/^/^Modified, not completely thermoplastic: Asphalt cold patch material is a modified asphalt mixture, which has the significant advantages of direct injection and high performance./^/^Good stability: At normal temperature, asphalt cold patch material is liquid and thick, with stable properties. It is the core raw material for cold patch production./^/^Wide range of application: It can be used between -30℃ and 50℃, and can be used all-weather. It is suitable for repairing various types of road surfaces in any weather and environment, such as asphalt, cement concrete roads, parking lots, airport runways, and bridges. Scenarios such as expansion joints, potholes on highways, national and provincial highways and municipal highways, community excavation and filling, pipeline backfilling, etc./^/^No heating required: Compared with hot mix, asphalt cold patch material can be used without heating, reducing energy consumption and emissions./^/^Easy to operate: When using, just pour the cold patching material into the pits and compact it with a shovel or compaction tool./^/^Excellent performance: Asphalt cold patch material has high adhesion and cohesion, can form an overall structure, and is not easy to peel and move./^/^Convenient storage: Unused asphalt cold patch material can be stored sealed for subsequent use.
