Joint Sealants

We are offering crack and joint sealants. Roadphalt crack and joint sealants
technology background
pavement cracks were affected by the temperature, rainwater, traffic loading and various of factors ,have formed a kind of complex and difficult to treatment of pavement disease.
The traditional pouring material will be re-crack in a short time due to itself low temperature brittleness, high temperature stability, easy to aging and other defects.
Roadphalt pouring technology overcomes the traditional pouring defects on the material properties and the use of methods.

(a)crack types and treatment methods
different crack types need use different corresponding method of treatment.
 â â transverse cracking
longitudinal cracking
net cracking
massive cracks
1.transverse cracking
: cracks from the shoulder to shoulder, or through the shoulder to the centerline, divided into temperature fatigue cracks and semi-rigid reflective cracking.
Whether can pouring : yes
2. Longitudinal cracking
:cracks is nearly parallel with the centerline of the road. The main reason for the formation of cracks in the pavement cannot meet the structural strength of the heavy traffic.
Whether can pouring : yes
3.net cracking
cracks in pavement cracks are multiple connectivity together to form a multilateral, acute angle pieces, develop into a mesh of cracks.
Whether can pouring : no
4. Massive cracks
:massive crack is caused by the amount of traffic loading and transportation or roadbed material damage.
Whether can pouring : no
