About the Location
Located along Barton Road in the City of Loma Linda, CA, this project leveraged the preservation of BioSpan's RePlay to sustain older asphalt streets and delay reconstruction. The goal is to stretch the lifespan of deteriorating surfaces and rebuild the municipal budget to incorporate an efficient preservation program. The project was completed in the late summer of 2025 in partnership with BioPave Services LLC and Mike Roquet Construction.
The Challenge:
The project targeted aging and cracked roadways—some older than 12 years with estimated pavement condition indexes (PCI) below 55—in California’s environment amidst busy city traffic.
The Solution:
RePlay was applied to 4 lanes on both sides of the median of Barton Road, between the intersection of Mountain View Avenue on the west end to the railroad crossing on the east end. RePlay was also applied to several intersecting asphalt streets to monitor different surface conditions, pavement ages, and traffic volumes.
The Result:
Application was managed in several working sections to limit traffic disruption an maintain efficient treatment. The public works director anticipates the strong potential of biobased preservation to sustain longevity and delay more costly reconstruction.
Project Breakdown:
After witnessing firsthand the "non-aging" asphalt pavements in one of their subdivisions—where the PCI was maintained at 85-–the public works director decided to implement more RePlay usage for the city’s benefit.
They asked BioPave Services LLC. to test RePlay treatment on an existing pavement with a much lower PCI—around 55-–to determine how much more life can be maintained. The public works director’s goal was to maintain this pavement a little longer, delay the cost of repaving, and help rebuild municipal budgets with a plan to include RePlay in their rejuvenation and preservation toolset (along with micro-surfacing and mill-and-fill projects). BioSpan’s RePlay was applied to both the eastbound and westbound 4-lane highway on either side of the median, using an estimated 1100 gallons in total.

RePlay effectively creates a high-performance, polymer-modified and rubberized asphalt pavement surface that can withstand the UV exposure and oxidation of Southern California’s environment. It will maintain durability of the existing asphalt and resist further crack propagation under busy traffic conditions.
