When thinking about the conditions a parking lot pavement needs to withstand, imagine a parking lot in Michigan in January, or other areas that are exposed to freezing and thawing, deicing chemicals, and heavy loads. Any of these factors can, and will, destroy concrete that is installed with a mix that isn't properly proportioned. Here are a few of the reasons why a building owner should pave his parking lots with concrete: The pavement designer can use this nomograph and an iterative technique to come up with the pavement thickness based on the subbase strength and the anticipated loads. PARKD Ltd is an Australian construction technology company that has created an innovative modular, multi-storey carpark structure called the Parkd Car Park System. Over its lifetime, the most expensive pavement is a typical asphalt pavement which is cheaper to build initially, but is under-designed in load-carrying capacity and ends up with high maintenance costs. ACI Committee 362, (2012) Guidelines for the Design and Construction of Durable Concrete Parking Structures, American Concrete Institute, Farmington Hills, Michigan. Operating globally from over 70 countries, we have the extensive product range, expert knowledge and technical support to assist with your refurbishment project. A well-thought-out jointing pattern will prevent random cracks. Edges can be thickened by using an integral curb or by thickening the bottom (see diagram).

Find more info on, A good idea for a successful project is to hold a pre-placement conference with the designer, the owner, the concrete producer, the general contractor, and the concrete contractor. The nomograph shown here will yield a design thickness knowing the subgrade reaction (k), the expected loads (how heavy the vehicles will be), and the number of load repetitions expected over the 20-year pavement life.

Find more info on, Joints should be sawed as soon as possible without raveling the concrete-from 4 to 12 hours with conventional saws and 1 to 4 hours with early entry saws. Setting side forms and using hand screeds, truss screeds, or other vibrating screeds is another option, and probably the most common. For years, contractors have emphasized concrete’s lower life-cycle costs based on its longer life span and lower maintenance needs. Watchmead Precast concrete is widely used in the construction of multi-storey car parks. The construction work was completed on the remaining parking levels in the first half of 2016 with the result that the city centre is richer by a further 485 new parking places. Precast concrete lends itself well to these buildings due to its overall structural strength and durability. Slope of entrances to the parking lot should not exceed 8% to prevent cars from dragging.

Slipforming is fast and produces very high-quality pavement, although the equipment is expensive and positioning the equipment is difficult except for on very large lots. A well-detailed concrete car park… Similarly, dowels at joints to transfer the vertical loads between panels are unnecessary unless very heavy loads are anticipated—as for heavy truck traffic. Sika manufacture a range of car park deck waterproofing products suitable for top decks & exposed areas, intermediate decks, ground bearing slabs and ramps. Install with rebar stakes. AL7 1BQ Maintenance costs for concrete are nearly zero—only some joint sealing and annual cleaning. Heavy trucks can cause pumping of the subbase and result in a loss of support beneath the joint—in that case, joint sealing is necessary. Welwyn Garden City You could fog-cure, but that's probably more effort than it's worth for most parking lots. Find more info on. It classifies car parking facilities according to the type of use as shown in Table 1. Joints are cut on a 3- to 4-foot grid. K2 has multiple systems; K1 – A specialist steel and concrete option with unique design and own modular steel frame solution which uses in-situ concrete cast in trays to provide either a single deck or a full multi-story car park. The durability of the structural frame is an important aspect of car park design. Pavement durability relies on a good surface layer, freeze-thaw resistance and overall strength. Maintenance for an asphalt lot can be as much as 80% of the initial construction cost; and on one Florida project, asphalt was shown to be twice the cost of a concrete lot over 20 years. The lighter color also results in a lower temperature for the parking area during the summer, reducing the heat-island effect and lowering cooling costs for adjacent buildings. ACI 330R-01. Well-graded mixes are more workable and also shrink less (and therefore crack and curl less). For RCC a zero-slump concrete is placed with dump trucks and rolled with heavy vibrating steel rollers.
