Lonestar Highway Products manufactures Safety Pipe Runners for all Texas Department of Transportation specifications.

These applications include but are not limited to:

• Parallel Drainage Safety Pipe Runners (PD-SPR) PD-SPR type I shall be used on single or multiple reinforced concrete box culverts (RCB), either precast or cast in place, or type II reinforced concrete pipe (RCP) or corrugated metal pipe (CMP) with the ends tapered to the proper slope as shown on Texas Department of Transportation (TxDOT) standard drawing B16, unless shown otherwise in the contract documents.

• Cross Drainage Safety Pipe Runners (CD-SPR) CD-SPR type I shall be used on single or multiple reinforced concrete box culverts (RCB), either precast or cast in place, or type II reinforced concrete pipe (RCP) or corrugated metal pipe (CMP) with the ends tapered to the proper slope as shown on Texas Department of Transportation (TxDOT) standard drawing, unless shown otherwise in the contract documents.

Pipe Runners conform to – ASTM A53, Grade B or equivalent strength pipe.

Unless otherwise shown on the drawings, all metal pipe, plates, angles, nuts and bolts shall be galvanized in accordance with ASTM A123, or A153, whichever is pertinent.

Lonestar Highway Products can provide Precast Safety End Treatments for pipe sizes 12″ – 48″ with slopes 3:1 to 6:1.

Specifications:

1. Concrete: Has a Design Strength of 5,000 psi at 28 Days
2. Steel Reinforcement: ASTM A-615, Grade 60 or ASTM A-497 Welded Wire Fabric
3. Loading: Designed for H20 Loading
4. C.I. Castings: ASTM A48, Class 30/35

General Notes:

1. Class “C” Concrete
2. All Exposed Corners shall be Chamfered 3/4″

Lonestar Highway Products can provide reinforced steel for the following applications:

• Concrete Paving
• Bridges
• Small Structures
• Flat Work
• Safety End Treatments

Specifications:

• Steel Reinforcement: ASTM A-615, Grade 60

Lonestar Highway Products can provide Corrugated Metal Pipe for uses in Drainage, Flood Control and Sewer Systems.

It is economical, strong and durable. The pipe is usually fabricated 20 foot sections; however, it can be fabricated in any length up to 40 feet, offering the contractor flexibility and ease of installation not found with other types of pipe.

Diameters range from 6 inches to 12 feet and in thickness from 18 gauge (.052) to 10 gauge (.13). The span and depth of corrugation vary with the diameter and guage of the pipe, the most common being one-half inch (depth) two and two thirds inch (span, crest to crest). For larger pipe (48 inches and up) a deeper corrugation (one inch by three inches) is available for additional strength.

Lonestar Highway Products can provide TxDOT approved catch basins, drop inlets, median drop inlets, junction boxes, driveway trench inlets and other custom-designed products.

Sanitary and sewer manholes are sized to meet any need from 4′ to 10′ size inside diameter.

Specifications:

1. Concrete: Has a Design Strength of 5,000 psi at 28 Days
2. Steel Reinforcement: ASTM A-615, Grade 60
3. Loading: Designed for H20 Loading
4. C.I. Castings: ASTMA-48, Class 30/35

Lonestar Highway Products can provide Precast Concrete Box Culverts where situations call for depth or height restrictions or where the use of concrete or metal pipe cannot provide adequate flow capacity.

Precast Box Culverts are normally avaliable in spans of 3 feet (.914m) through 12 feet (3.6m), with a variety of rises.

Applicable specifications:

• ASTM C1433 – Precast reinforced concrete box sections for culverts, storm drains and sewers
• AASHTO M259 – Precast reinforced concrete box sections for culverts, storm drains and sewers
• AASHTO M273 -Precast reinforced concrete box sections for culverts, storm drains and sewers with less than 2 feet of cover, subjected to Highway Loads

Advantages:

• Miminum Traffic Delays
• Assured Quality Control
• High Early Compressive Strengths
• Quick Project Completion
• Ease of Installation – 8′ and 6′ laying lengths with a tongue/groove joint – culvert pipe installation
• Readily Available

Lonestar Highway Products can provide Reinforced Concrete Pipe from 12″ through 72″.

Strength classes are available from II to III to IV to V and “special design” to meet project load requirements.

Concrete pipe continues to be the choice when durability, structural integrity, 100 year design life, constant hydraulic efficiency, and low maintenance are considered. The strength of concrete pipe also plays an important role in a bedding and backfill requirements. Because concrete pipe also acts as a structure it is less dependent on the soil placed around it. Concrete pipe won’t rust, buckle, split, deflect, deteriorate, burn, pollute, waste energy or loose it’s hydraulic capacity.

Specifications:

• ASTM C76 – Standard specification for reinforced concrete culverts, storm drains and sewer pipe
• ASTM C443 – Standard specifications for joints, for circular concrete storm sewer and culvert pipe, using rubber gaskets
• ASTM C655 – Standard specification for reinforced concrete de-load culvert, storm drain and sewer pipe
• AASHTO M170 – Standard specification for reinforced de-load culvert, storm drain and sewer pipe
• ASTM C506 – Standard specification for reinforced arch culvert, storm drain and sewer pipe
