When applied early in the pavement's life cycle, it can cost-effectively extend surface life by seven or more years. Slurry seal — Applied to existing pavement by a spreader box linked to the surface slurry-mixing unit. Used over newly laid pavements, slurry seal will prevent surface distresses such as the effects of weathering.

Conventional Emulsion Cape Seals cost about $1.00 to $1.25 less per square yard than an Asphalt-Rubber Cape Seal. Conventional Emulsion Chip and Cape Seals last about 6 to 8 years on roads with 1/8" to 1/4″ alligator cracks. Asphalt-Rubber Chip and Cape Seals last about 12 to 15 years on roads with 3/8" to 1/2″ alligator cracks.

Slurry seal is a mixture of quick setting asphalt emulsion, fine aggregate, mineral filler, additives, and water. This procedure is smoother than a chip seal treatment, yet has the same affects. Cape seal is an application of chip seal which is then followed by slurry seal. This not only increases the life but as well binds the loose aggregate.

Generally, the estimated life for a micro surfacing application varies between 4 and 8 years of service, depending on traffic conditions. The life expectancy of a slurry seal is estimated between 3 and 7 years. It is not uncommon to see both types of applications exceed these periods of service. However, if a slurry

In this way, asphalt pavement life can be substantially extended at comparatively low cost. Of course, slurry seal can be used to address certain pavement distresses in addition to its pavement preservation benefits. In doing so, it is important to understand the life expectancy of the slurry seal decreases as the distress severity increases.

The longevity of a slurry seal is dependent on both traffic volume and the weather, but the average life expectancy of slurry seal is 4-7 years. What is slurry seal used for? Slurry seal is used to correct minor defects in pavement such as halts, raveling, loss of matrix or skid resistance to extend the life …

Slurry Seal has a life expectancy of approximately 6-8 years. Chip Seal# Chip Seal is used to maintain, protect and prolong the life of an existing street or road. It will improve the skid resistance to allow for a safer driving surface, improve the overall appearance, provide a weatherproof membrane to repel moisture from damaging the base and ...

To achieve effective pavement maintenance, the life expectancy and timing of treatment applications need to be determined. The Long Term Pavement Performance (LTPP) program includes the Specific Pavement Study-3 (SPS-3), which focuses on this subject. The treatments applied are chip seals, crack seals, slurry seals, and thin overlays.

Most seal manufacturers say that operation of the seal at one of these limits will result in a minimum life span of two years; three years with some seal types such as those specified in Standard API 682. The published limits, while reliable for steady state operation, may be overstated or unreliable for cyclic operation.
