Government / Public Agencies

Union Pavement Services applies Caltrans Section 37 treatments such as slurry seal, micro surfacing and cape seal to a wide range of State, County and City roads throughout the State of California. We proudly serve as a subcontractor to a large number of prime infrastructure contractors who require our services to take care of their project’s pavement preservation needs. These agencies know that a properly maintained pavement can last for many years, as most of these agencies have typically been performing these techniques for decades in California.

Slurry Seal & Micro Surfacing

These Caltrans-approved products correct minor deficiencies in the pavement surface and provide a nice new wearing course that will extend pavement life by 8-12 years. We can enhance these products with the use of aesthetically pleasing darker aggregates or fiber for slowing down future cracking.

Common Multi-Layer Pavement Preservation Systems

Chip Seal + Slurry Seal (or Micro Surfacing): A chip seal may be applied first to seal and reinforce the surface, followed by a slurry seal or micro surfacing application to smooth the surface and fill minor cracks.
Crack Sealing + Micro Surfacing: After cracks are sealed, a micro surfacing treatment may be applied as a final layer to restore the surface texture, fill remaining cracks, and improve skid resistance.
Prime Coat + Chip Seal + Fog Seal: A prime coat is applied to prepare the surface, followed by a chip seal to seal and protect the road, and a fog seal to enhance the appearance and further protect the surface.
Slurry Seal + Rejuvenator: Slurry seal is used for surface sealing and texture restoration, while a rejuvenator may be applied between layers to restore the flexibility and waterproofing properties of the aging asphalt.
Micro Surfacing + Chip Seal + Slurry Seal (3-Step Application): This process has been used for decades throughout California. It used over structurally sound, but severely alligatored and aged pavements. It involves a Type III leveling micro surfacing course, followed by a chip seal and a slurry or micro surfacing wearing course.

Slurry or micro surfacing systems are the standard when it comes to cost effective wearing courses for most multi-layer systems. Either technology is effective depending on local conditions. Micro surfacing can be installed during nighttime conditions in traffic sensitive areas or in problematic climates. The systems can be made to increase skid resistance or provide the public with the smooth local roads they desire.

Surface Preparation Work

Union Pavement Services has the resources needed to perform and preparatory work such as asphalt patch repairs, crack sealing or striping removal that may be required prior to the completion of resurfacing work.
