Problems solved by technology

But in fact, since the rain is basically acidic rainwater, there will be bubbles in the process of rainwater falling down, and these bubbles will increase the gap between the layers, resulting in the gap between the layers. The strength of the connection is reduced, eventually causing the entire runway to crack into multiple segments

Abstract

The application discloses a novel environment-friendly mixed type plastic runway comprising a pre-paving layer, a base layer, a reinforcing layer and a surface layer. The pre-paving layer is used formaking contact with a cement layer on the ground. The base layer is arranged above the pre-paving layer, the reinforcing layer is arranged above the base layer, and the surface layer is arranged abovethe reinforcing layer. The pre-paving layer comprises 30-40 parts of cement, 24-30 parts of sands, 10-15 parts of pumice stone, 1-3 parts of activated carbon powder, 1-3 parts of aluminum oxide powder, 1-2 parts of copper powder, 2-5 parts of polypropylene fiber and the balance being water. Compared with the prior art, the novel environment-friendly mixed type plastic runway has the following beneficial effects that the mixed type plastic runway prepared from the components is good in water permeability, high in friction strength between layers, free of layering and cracking, high in pressureresistance and deformation resistance and capable of bearing running of heavy vehicles.

Description

technical field [0001] The invention relates to the field of runways, in particular to a novel environment-friendly hybrid plastic runway. Background technique [0002] Now the amount of construction of hybrid plastic runways is increasing. Patent CN108193578B provides a hybrid plastic runway, but there is a problem in this hybrid plastic runway. Sodium carbonate is placed. The purpose of placing sodium carbonate is to take advantage of the property that sodium carbonate is easily soluble in water. It is expected that it can be dissolved in water in rainy days or artificial watering, so that the base layer, reinforcement layer, and surface layer can all have water seepage holes. Further The water seepage performance of the whole plastic runway is enhanced. But in fact, since the rain is basically acidic rainwater, there will be bubbles in the process of rainwater falling down, and these bubbles will increase the gap between the layers, resulting in the gap between the layer...
