Bituminous pavement structure, resonant rubblizing composite base layer and production method thereof

Abstract

The invention provides a bituminous pavement structure, a resonant rubblizing composite base layer and a production method thereof, which belong to the field of bituminous pavement construction. The method comprises the following steps: lean concrete is poured on a roadbed to form a lean concrete layer, and slurry containing cement and stone chips on the lean concrete layer is taken as a raw material to form a vibration-isolation layer; concrete is poured on the vibration-isolation layer, and a concrete slab is formed; the concrete slab is subjected to resonant rubblizing processing so that the concrete slab is fragmented, and a resonant rubblizing layer is obtained; and the lean concrete layer and the resonant rubblizing layer integrally form the bituminous pavement resonant rubblizing layer composite base layer. The bituminous pavement resonant rubblizing layer composite base layer has comprehensive coordination effect for mechanics characteristic, function characteristic and long-time deterioration rule and damage characteristic, can permanently compatible with a bituminous pavement layer, fatigue cracking of the bituminous pavement layer cannot be generated; the resonant rubblizing composite base layer is adapted with the roadbed bearing capability, humidity condition and soil types, and long life of the bituminous pavement is ensured.

Description

technical field [0001] The invention relates to the field of asphalt road construction, in particular to an asphalt pavement structure, a resonance crushed petrification composite base and a manufacturing method thereof. Background technique [0002] In the past, China's cement roads and asphalt roads first needed to solve the problem of getting rich, but with the development of the national economy in the new era, the existing roads with a short service life can no longer meet the actual production and living needs. On the one hand, the people who have become rich will also bear the huge overhaul costs accumulated over the years for a long time, and a large number of cement concrete pavements have become problematic pavements that urgently need to be renovated. On the other hand, the transformation and overhaul of existing roads affect people's traffic and travel. Therefore, the construction of long-life asphalt roads is the need of the new era. [0003] At present, domes...
