Composite mixture materials made of recycled plastic, glass and rubber, and optionally sand, gravel and metal and containing no petroleum distillates, unless a fire retardant or recycled pavement is used are disclosed. Methods of using the composite mixture materials include making expansion joints in pavements, and making panels, walls, blocks, impact protection walls and oth er such structures. Methods of making the composite mixture include heating the components of the material in inert gas in environmentally friendly manner. Compressive pressure is applied to composite mixture materials in making expansion joints, manhole cover recess fillers and filling potholes to build in an elastic strain to overcome both composite material shrinkage on coolin g solidification of the material and the thermal contraction of pavement as shown in Figure 4. |
