Pothole Repair for Asphalt and Concrete Base Aggregates

Technology Application

Pothole repair Asphalt Cement

Detailed Technology Description

Researchers at UCLA have developed a strong bonding polymer that offers a long-term solution to asphalt and cement pothole repair patching material. Because the new polymer has high fracture toughness and impact absorbing ability, it serves as a continuous structural cage material for holding aggregates together even when heavy traffic stresses are applied. Furthermore, due to its adjustable viscosity, the material provides penetration depth control for various applications.

Title: APPLICATION OF HIGH TOUGHNESS, LOW VISCOSITY NANO-MOLECULAR RESIN FOR REINFORCING POTHOLE PATCHING MATERIALS IN ASPHALT AND CONCRETE BASE PAVEMENT
Usefulness: APPLICATION OF HIGH TOUGHNESS, LOW VISCOSITY NANO-MOLECULAR RESIN FOR REINFORCING POTHOLE PATCHING MATERIALS IN ASPHALT AND CONCRETE BASE PAVEMENT
Summary: The method is useful for increasing a durability of concrete such as asphalt concrete and cement concrete including portland cement, masonry cement, mortar cement, gypsum, calcium aluminate cement, hydratable alumina, hydratable aluminum oxide, colloidal silica, silicon oxide, magnesia, limestone, hydrated lime, pozzolans, fly ash, granulated blast furnace slag, metakaolin, rice hull ash, silica fume, oil well cementing grout and hydraulic cement binder, where the concrete is useful: in a preformed article such as precast concrete wall, barrier, block, post, beam, road section, bridge component, railroad tie, junction box, grate inlet, culvert, swimming pool, section of swimming pool, foundation, safe room, crypt, housing component, architectural form and sculpture (all claimed); in the formation of a road or runway, a structural device or surface, and an ornamental device or surface; for repairing a damaged surface; in the building or reinforcement of structures or barriers to reinforce military or secure areas; and in concrete barriers on highways.
Novelty: Increasing a durability of concrete e.g. cement concrete including portland cement that is useful in a preformed article e.g. junction box, comprises infusing a concrete with an oligomeric solution, and forming a thermoset polymer

Background

The occurrence of potholes on asphalt and cement pavements are long standing issues. Previous repair methods offer only temporary solutions as traffic stress cause a portion or whole block of the repaired material to separate from the original pothole. In order to boost the lifetime of the repaired potholes, it is necessary to employ strong bonding material with high fracture toughness that can absorb energy without breakage.
