Street & Highway Drainage
ADS corrugated polyethylene pipe is used extensively for cross drains, culverts, and underdrains in roadways throughout the nation.
It has three to five times the service life of corrugated metal pipe, is far lighter in weight and easier to install than concrete pipe, and is still strong enough to endure soil pressure at depths of 30 m. High density polyethylene is also tough enough to handle the most abrasive runoffs as well as the tensile stresses involved in relining existing pipes.
New! ADS applauds recent action by the Federal Highway Administration (FHWA) to change its national 'construction and maintenance' regulation applying to the use of alternative types of pipe on Federal-aid highway projects and has issued a press release. The regulatory change, which became effective December 15, 2006 was made to ensure that state departments of transportation (DOTs) provide for competition in their specifications of types of storm water drainage pipe, thus promoting greater efficiencies and cost-saving in the use of transportation tax dollars.
The government's regulatory change is being made in the context of the need to find additional ways to stretch limited taxpayer dollars devoted to highway and bridge improvements around the country. While federal highway investments have increased over the years, the recent spikes in the prices of steel, cement and other commodities have seriously decreased the purchasing power of those dollars. Requiring robust competition among alternative construction products and materials – including those in drainage – is seen by government agencies like the FHWA as one of the best ways to create efficiencies and reduce costs. ADS has worked hard over the years to introduce its cost-efficient HDPE products into the highway construction arena.
Applications within this Market
- Cross Drains
N-12 HDPE corrugated pipe from ADS features a corrugated exterior giving it the strength needed to withstand cross drain installations.
- Edge Drains
High-traffic roads need to be drained quickly. Panel-shaped AdvanEDGE pipe offers fast drainage response and is perfect for all time-critical applications.
- Slope Drains
ADS pipe is used in slope drain applications to help with erosion control. Single-wall pipe is the most common pipe installed in slope drains.
- Erosion Control
ADS erosion control mats effectively reduce landscape deformation and hold vegetation firmly in place.
- Surface Drainage
Sitting water can devastate a roadway. An ADS drainage system helps keep the pavement dry with little, if any, maintenance.
ADS pipe's durable design can withstand H20 and E80 loads, making it the ideal choice for all culvert installations.
Street and Highway Drainage Products
The nation’s growth and viability depends on a sound infrastructure, and storm water management is a critical component to insure the long-term success of our roads and thoroughfares. ADS offers the industry’s widest array of storm drainage products to meet the critical demands of the engineering design and contractor communities.
- N-12® (per AASHTO)
Since introducing corrugated dual wall pipe in 1986, N-12® pipe has become accepted across the nation as a superior alternative to reinforced concrete pipe and corrugated steel pipe. N-12 pipe is used for cross drains, parallel drains, underdrains and culverts. Available in 100 mm–1500 mm diameters, N-12 pipe offers superior hydraulics combined with corrosion and abrasion resistance, to provide a strong durable choice for highway and roadway storm water management.
- N-12® (per CSA)
N-12 ® (per CSA B182.8) pipe is the Canadian standard for corrugated polyethylene drainage pipe. Introduced in 2002, N-12 dual wall pipe with its smooth interior wall and corrugated exterior wall, offers exceptional hydraulics and strength. Built using application specific high-density polyethylene, N-12 corrugated pipe also provides superior corrosion and abrasion resistance making it an excellent alternative to reinforced concrete and corrugated metal pipe. These properties have led to the increasing approval and acceptance of N-12 drainage pipe in storm water applications across the country. The certification of our N-12 pipe is by a third party agency accredited by the Standards Council of Canada.
- Nyloplast® Drainage Structures
Constructed from heavy duty PVC, Nyloplast structures are the exceptional choice over heavy and cumbersome concrete manholes and drain basins. Drain basins, curb inlets, and inline drains are all easily installed with minimum equipment and manpower. Capable of handling H-20 loads, Nyloplast structures provide a watertight seal with excellent economics.
- Geosynthetics/Geogrids Erosion Control
ADS offers a complete line of woven and non-woven geotextiles, geogrids and other road stabilization and erosion control products to support road and embankment construction through our relationship with SI Geosolutions and other national manufacturers.
- Single Wall
Our perforated and non-perforated single wall pipe, in 75 mm–600 mm diameters are ideal for drainage plans where flexibility, light-weight durability and economics are key to the overall success of the project. From highway edge drain pipe to culverts for rural and other state roads, corrugated single wall polyethylene pipe outperforms corrugated steel in chemical and abrasion resistance.
Our panel-shaped, geo-composite pipe is engineered for highway edge drains where a quick drainage response is required. Its unique flat shape and structural support creates a large surface area with a small installation footprint. It is easily installed using common plow-in equipment.
