The first segment roads were built by the Minoans about 5,000 years ago. The Romans built the first segmented interstate system, which was longer than the current US interstate highway system. Most would agree that paving stones offer the beauty and charm of the “old world”, but the strength and durability of blocking pavers are often overlooked in North America. In this article we will talk about the fundamentals of interlocking pavers and consider common misconceptions about paving.
It is important to understand that the installation for paving stone is an engineering system; paving stones are just a part of this system. Components of laying paving stone from the bottom up are: compacted subclass (or soil layer), geotextile fabric, compacted filling base, sand for sand, edge limiter, asphalt paver and joint sand. Unlike in-situ cast concrete, interlocking pavers are flexible pavement. It is this flexibility that allows you to transfer a point load from a truck or car tire and distribute it through the base layer to the subclass. By the time the load reached the sub-class, the load was distributed over a large area, and the subclass was not deformed.
Concrete, on the other hand, is a hard pavement. Its function is to simply wash the soft spots in the soil. Poured concrete will crack and break due to stress, shrinkage, soil expansion and increased frost resistance of the subclass. Concrete is one of the most important materials in construction, but, in fact, concrete makes a concrete surface. This is due to its relative accessibility to flexibility and low tensile strength. Reinforcement reinforcement and reinforcement can increase the tensile strength of concrete, but cracking and tearing is inevitable.
Modular paving stones are usually made of hardened precast concrete or kiln. Properly installed pavers are blocked, so the load on one paver is distributed between several pavers and historically transferred through the base layer. The factors affecting the blockage are the thickness of the lane, the shape of the stacker, the size of the stacker, the width of the seams, the pattern of stacking and the limitation of the edge. Most platform manufacturers offer a lifetime warranty when their products are professionally installed. Natural stone, such as Flagstone and Bluestone, is not suitable for flexible styling, and they are usually installed on a concrete slab. Since the pavers are paired with sand (instead of mortar), they can be lifted and replaced inexpensively. For example, paving stones can be raised to access underground utilities and restored when work is completed.
Paving designs are based on variables that include soil makeup, expected stress, climate, groundwater level and rainfall. The materials used for aggregate base and sandy sand differ geographically. Soils with a high content of clay and loam are unsuitable for compaction and cannot be used as the main material; in these cases, graded rubble is replaced. Proper compaction of the material of the subclass and the base material is crucial for the long-term operation of the protection system, and in automotive applications the depth of the compacted base can be more than 12 inches. The edges of the stacker installation should be limited to ensure blockage and prevent lateral creep. The most common types of boundary stops are embeddings from plastic edges, precast concrete curve and concrete concrete. Materials for bedding include angular sand, sand and polymer sand.
The beauty and durability of the paving system is determined by its designer and installer. Properly installed pavers offer lifelong paving. Incorrectly installed pavers can fail within a few years. When choosing an installer, pay attention to training, experience and links.
FAQ & # 39; s
Q: Are pavers permeable (or permeable)?
A: Most stacker installations are impenetrable (impenetrable). However, most manufacturers offer permeable pavers that are installed on an open graduated basis. The permeable system is designed to store water in the base material, so it can be released back into the soil. These systems reduce runoff, feed groundwater and eliminate the need for storage ponds.
Q: Can pavers be installed on a steep slope?
A: Yes, paving stones work very well on steep slopes, but joint erosion can occur during heavy precipitation. In these cases, polymers are added to the joint sand to prevent sand washing.
Question: Do pipers look after time?
A: Settlement is almost never a problem with properly installed pavers. However, soft areas in a subclass should be considered before placing the base. Dust pits and decomposing organic material should be removed and replaced with compacted base material.
Q: Can pavers be used for highways?
A: Bridge systems can handle huge loads, and for this reason they are often used at airports and seaports. However, paving stones are not suitable for high-speed traffic and braking forces.
Question: Will paving stones help in my leak problems?
A: Water management is considered at the design stage. When there is very little slope or negative slope, surface drains; channel drains; and drainage lines are used to move water away from the structures.
Q: Will weeds grow in the joints?
A: Airborne weeds can take root in the sandy sand, but they are easy to control using weeds. Polymeric articular sand can be used to prevent weed growth and stabilize joints.
