The rigid pavement is basically the plain concrete,
or reinforced concrete slabs laid directly over
the Dry Lean Concrete or a stabilized base course.
The cement concrete slab has a very high modulus of elasticity;
therefore, the deflection of the slab is very little
under the vehicular load, hence they are very suitable
for carrying high traffic loads. While rigid
pavements have a higher initial construction
cost about 1.5 times that of flexible pavements,
they offer a longer service life and lower
maintenance costs. However, factors like geological
movements, faulty design, inaccurate traffic volume
predictions, subpar workmanship etc., can significantly
impact the overall performance and reduce their expected
lifespan. Hence to address these challenges and extend the
life of rigid pavements, timely and effective maintenance is very crucial.
Given the vast scope for maintenance and the lack of organized players in this field, we have established a exclusive team dedicated to rigid pavement maintenance and rehabilitation. The Division specializes in the rehabilitation and maintenance of concrete pavements, ensuring long-lasting and durable solutions. With a focus on quality and innovation, we employ advanced techniques and adequate materials to repair and rehabilitate rigid pavements, extending their lifespan and improving the performance.
Our team of experts with extensive experience in technical due diligence and investigation is dedicated to delivering cost-effective and sustainable rehabilitation services, tailored to meet the specific needs of Customers. We pride ourselves on our commitment to excellence, timely execution, and customer satisfaction, making us a trusted partner in the industry.
Rigid Pavement failures are broadly categorized into two categories where we as MARKOLINES offer our services:
Structural Distresses
These affect the pavement's load-bearing capacity and are typically caused by excessive loading, improper joint spacing, and material issues.
- Structural Cracks: These can compromise the pavement's integrity. Partial or complete panel replacement is the solution offered.
- Damage to DLP/GSB/Subgrade: Depending on the extent of the damage, full or partial depth replacement is adopted to mitigate the issue.
Functional Distresses
These affect the riding quality and safety but do not significantly impact load-bearing capacity.
- Plastic Shrinkage Cracks, Edge Cracks, Corner Cracks, Punchouts, Pop-Outs, Transverse, Longitudinal, and Diagonal Cracks are developed affecting the riding quality. To cater to this we use stitching or stapling, depending on severity.
- Raveling and Roughness: Treated with partial depth repairs using speciality chemicals.
- Separation at Joints and Sealant Failure: Micro concrete or speciality chemicals are used for partial depth rehabilitation, depending on damage severity.
