Stress Absorbing Membrane Interlayer (SAMI) Asphalt Paving to Stop Reflection Cracks

prevent reflection cracks on asphalt pavement


1. Description

    Stress Absorbing Membrane Interlayer (SAMI) Asphalt Paving is used as the combination layer of the roadbed and the surface layer, or the lower layer of the surface layer. On the other hand, it can prevent the surface water from seeping into the subgrade and cause damage to the subgrade.
    Reflective cracking is a common disease in asphalt pavement. Reflective cracks destroy the integrity of the road surface and affect the appearance of the road surface. Water enters the base layer through the cracks to accelerate the destruction of the asphalt pavement and seriously affect the performance of the asphalt pavement.

Reflection cracks
    ZTS Stress Absorbing Membrane Interlayer between the cracked structure layer and the asphalt overlay is an effective measure to prevent reflection cracks. It is an asphalt mixture with strong adhesion, impermeability, and good interface bonding performance, can deform with the deformation of the base layer, and has excellent self-healing ability.

Advantages of ZTS Stress Absorbing Membrane Interlayer (SAMI) Asphalt Paving:

  • Good adhesion, low temperature resistance and fatigue resistance.
  • Resistance to high temperature deformation.
  • The construction workability of the asphalt mixture is better.
  • Construction is more convenient by using ordinary asphalt paver.
  • No special modified bitumen and special equipment are needed in the production and construction process, the cost is more lower.
  • Environmental protection, no restrictions on asphalt paving.


2. Special additive for Stress Absorbing Membrane Interlayer (SAMI) Asphalt Paving

    ZTA-VE asphalt additive are a new type of composite asphalt additive developed by Beijing Zhongtian Road Tech Co. Ltd. It integrates the technical characteristics of high viscosity, high elasticity, wide temperature range, and warm mixing to improve the crack resistance and fatigue resistance of road materials, reduce the difficulty of road construction, energy saving and environmental protection.

3. Production and Construction of Asphalt Mixture of Stress Absorbing Membrane Interlayer (SAMI) Asphalt Paving

    When mixing ZTS mixture, firstly add all grades of aggregate and VE high-elasticity anti-cracking additive for dry mixing, then add bitumen and mineral powder, and the mixing time is not less than 45 seconds, of which ZTA-VE additives and aggregate are dry mixed for 10 seconds. The temperature control requirements are shown in Table 2.

Table 2 Temperature control table for mixing and construction

Construction StageTemperature
Bitumen heating temperature140℃~150℃
Mineral heating temperature170℃~200℃
Asphalt mixture delivery temperature150℃~185℃
Asphalt mixture waste temperature>195℃
Paving temperature≥140℃
Initial compacting temperature≥135℃
Repeat compacting temperature≥125℃
Final compacting temperature≥70℃


The paving speed of asphalt paver is 3m-6m/min.
The repeat compacting roller needs to be rolled closely with the initial compacting roller.

The initial compacting adopts 13 tons - 15 tons of drum rollers
The repeat compacting adopts 20 tons - 26 tons rubber wheel rollers
The final compacting adopts below 11 tons of drum roller
(The vibration is not turned on during the rolling process)

Traffic can be opened only when the road surface temperature is lower than 50°C
