Composite mixture materials made of recycled plastic, glass and rubber,
and optionally, sand, gravel, coal combustion by-product and metal, and containing
no petroleum distillates (unless a fire retardant or recycled asphalt pavement
is used) are disclosed. Methods of using the composite mixture materials include
making expansion joints in pavement, filling manhole cover recesses, filling potholes
in pavement, making new pavements, and making panels, walls, blocks, impact protection
walls, and other such structures. Methods of making the composite mixture materials
include heating the components of the material in an inert gas environmentally
friendly manner. Compressive pressure is applied to composite mixture materials
used in making expansion joints, manhole cover recess fillers, and in filling potholes
to build in an elastic strain to overcome both a composite material shrinkage on
cooling solidification of the material and the thermal contraction of pavements,
and in making the composite material for any other of the uses disclosed.
