Although concrete pavers can be more expensive initially than asphalt or reinforced concrete, it is important to consider the cost relative to the life cycle of the pavement as well. The initial costs for materials and installation and the life cycle costs are considered direct costs and are easily quantifiable. There are however, external costs that are not as easily quantifiable but must be considered when determining pavement options. These costs include environmental impact, road user costs during repairs, integration of other requirements, redesign, pavement rehabilitation and aesthetics. The segmental and precast nature of the concrete paving units capitalize on several of these aspects while reducing lifecycle costs.

The indivual units of interlocking concrete pavements support the concept of a "zipper" which can be undone and then redone in a simple manner. Since the pavers are interlocked and not permanently attached to one another, it is possible to remove several individual units and simply replace them once a repair is made. The final result is undetectable and inexpensive. It is an immediate response to the need to gain access to the surface below or for the repair of damaged areas of the surface.

The foreman of a installation project is in charge of measuring and documenting productivity for the various job functions. In the end of a job the number of hours documented by the foreman are compared to the estimate that was given in the initial job bid. If the number of hours it took to complete the job exceeds the estimate then the job lost money, or was at least not as profitable. It is important for the job foreman to identify steps that can be taken in order to avoid hours that exceed the estimate.

Paver stones may need to be removed and replaced for a variety of reasons. Some pavers may start to sag and proper grade adjustments may need to be made, access to graded utilities may be a concern, or the paver itself may no longer be aesthetically pleasing due to chipping of the material or damage in some way. This clip will show you how to properly remove and replace a damaged paver.

The following video, brought to you by Woodie’s DIY, will show you the necessary equipment and steps it takes in order to seal interlocking pavers in a small area. Applying a sealer to pavers will not only improve their appearance but also protect the material from weather damage.

The first reason that concrete pavers – and any paver that interlocks – has to do with the material that they are constructed from. Concrete pavers are rated multiple times stronger than poured concrete. This is due in part to the way the pavers are formed, but it’s also due to the ‘interlocking nature’ of the material.

This Case Study is located along the Paseo de la Princesa in Old San Juan, Puerto Rico. This paseo, or promenade, runs along the base of the historic city walls of Old San Juan, the oldest planned city in the west- ern hemisphere, and is used annually by thousands of tourists and residents alike. 

The goal of this project is to better understand creative and thoughtful design approaches toward hardscapes through analyzing successful design projects that use segmental pavers.  The objective is to carefully observe and document a built design case study that is award-winning, successful, or otherwise highly regarded that uses segmental pavers as a key ingredient or focus in the design, and to then reflect on how pavers were applied in the design. 

Permeable pavements of concrete paving-stones for rainwater infiltration are established as a sustainable method for the drainage of traffic areas and for pollutant source control. Various systems for different applications exist. Pollutants like heavy metals and hydrocarbons in the runoff can endanger soil and groundwater, when the they are not sufficiently removed during infiltration.
