Abstract
A mixture formed from desired proportions of recycled asphalt shingle and recycled asphalt pavement is disclosed. The methods of molding the mixture into paving blocks, which exhibit properties of high compressive strength and low water absorption, are described. The paving blocks may be used to construct roads, parking lots, driveways, etc. A heated auger system for transferring the mixture to a molding system. The heated auger system can include concentric bodies to form separate concentric chambers, with one chamber receiving a heated fluid therethrough, and the other chamber for transporting the mixture through the auger system for heating by the heated fluid.
Claims20
A method of manufacturing one or more paving blocks using a mixture, the method comprising the following steps:
- (a) mixing recycled asphalt shingle particles and recycled asphalt pavement particles to produce a homogenous mixture thereof;
- (b) heating the homogenous mixture of step (a) to a temperature from 200 degrees F. to 425 degrees F. to form a heated mixture;
- (c) distributing the heated mixture into a molding system;
- and
- (d) applying pressure using the molding system to form the paving blocks.
A method of manufacturing one or more paving blocks using a mixture, the method comprising the following steps:
- (a) mixing recycled asphalt shingle particles and recycled asphalt pavement particles to produce a homogenous mixture thereof;
- (b) transferring the homogenous mixture of step (a) to a molding system using a heated auger and heating the homogenous mixture to a temperature from 200 degrees F. to 425 degrees F. while traveling through the heated auger;
- and
- (c) applying pressure using the molding system to form the paving blocks.
