Case StudyBear Valley Road Project (PDF)

Excerpt: A Rough History
Bear Valley Road is a heavily traveled road that also borders the City of Hesperia to the south (at the centerline – the south half of the road is in Hesperia), carrying approximately 55,000 vehicles each day, with 30% of them being trucks. Bear Valley Road is a heavily utilized, more direct route for traffic accessing I-15 from SR 18 to the east for areas including Apple Valley, Lucerne Valley, and Johnson Valley.
For many years an asphalt-paved street, Bear Valley Road was repaved with asphalt in 2004 but began to display rutting and deterioration immediately.

Thin Bonded Overlays in California & Nevada

Thin Bonded Concrete Overlays (TBCO) can be designed using a pavement design program like the American Concrete Pavement Associations StreetPave or the UTW tables found in “Whitetopping State of the Practice” ( ACPA EB21 OP). Many of the projects discussed in the following section were designed and constructed with longer joint spacings prior to the publication of State of the Practice but are performing acceptably. If it is desired to exceed the standard joint spacing, careful consideration should be given to the thickness and quality of the asphalt base and volume and weight of the traffic. Also, TBCO can only be used on asphalt pavement that needs a new surface treatment; it will not correct for asphalt pavement that is suffering from subgrade failure.

Roadbuilding and paving are no exception. That’s why engineers and public works officials are turning to a process called full-depth reclamation (FDR) with cement. This method rebuilds worn out asphalt pavements by recycling the existing roadway, reducing the raw materials and energy consumption.

The old asphalt and base materials are pulverized in place, mixed with cement and water, and compacted to produce a strong, durable base for either an asphalt or concrete surface. FDR uses the old asphalt and base material for the new roadway base. There’s no need to haul in aggregate or haul out old material for disposal. Truck traffic is greatly reduced, and there is little or no waste.

When asphalt pavements fail. determining the best rehabilitation procedure can be difficult. A simple asphalt overlay or a “mill and fill” approach can improve the appearance of the pavement surface, but may do little to correct the underlying problems that caused the failure in the first place. Within a short period of time the problems will likely reappear.

Long-term solutions to failed asphalt pavements include a thick structural overlay or complete removal and replacement of the existing base and asphalt
surface. Both methods can be very expensive and wasteful of virgin aggregates.

On average, 57,000 tons of cargo is pushed through the Port of Seattle’s Terminal 115 each month. Located just south of downtown Seattle, the terminal is occupied by Northland Services Inc., the port’s fourth-largest tenant.

The busy yard takes a lot of pounding, so when rehabilitation became necessary, special consideration was given to the available alternatives before deciding on a paving and pavement foundation method. A method of pavement rehabilitation known as full-depth reclamation proved to be the foundation method of choice, as it provided greater strength and durability than most of the other pavement alternatives.

Using Pervious Concrete to Earn LEED Points

Pervious concrete is a unique and innovative means to manage stormwater. When pervious concrete is used in building site design, it can aid in the process of qualifying for LEED Green Building Rating System credits. Pervious concrete has been used successfully in many types of construction on applications such as parking lots, streets, plazas, nature trails and walkways. While pervious concrete can be used for a surprising number of applications, its primary use is in pavement.

Storm Water Solutions – Bay Area Pervious Concrete

Imperviousness refers to the inability of a surface to allow water to percolate through. A sponge is pervious, a countertop is impervious, cardboard is somewhere in between. Sandy soils are pervious; asphalt is not. On an impervious surface, water is forced to travel downhill until it finds a place it can sink into soil or enter a wetland.
