RURAL ROADS · SENEGALSenegal Ministry of Transport

Village road stabilization in Senegal

Senegal's Ministry of Transport was looking for an alternative to conventional paving to strengthen village roads essential for transporting food, livestock and services. Midwest stabilized 6 km of village road using Soil-Sement® Engineered Formula (NaturalPave® system).

Challenges

Continuous pedestrian, vehicle and herd traffic (the road could not be closed, even for a day); unsuitable soils (10 cm of heavy clay at the surface, 10 cm of caliche, then 10 cm of good soil); no suitable equipment in the village.

Implementation

Cutting to a depth of 30 cm and blade-mixing the three soil layers; building a 20 cm base course in two 10 cm lifts, with wetting and compaction; incorporating Soil-Sement® Engineered Formula into a 10 cm surface course, graded and compacted; a final surface treatment for a durable, dust-free wearing course. Work progressed on one side of the road at a time to allow traffic and herds to pass.

Result

A significantly more stable, safer and more attractive surface, connecting rural communities with each other and with major commercial centers.

6 km: Village road stabilized
30 cm: In-place soils reworked, without imported material
Road open: Traffic maintained during construction

Road infrastructureColombia · Government of Antioquia

Field study across five Antioquia subregions

The Government of Antioquia studied rural road stabilization across 5 subregions.

Midwest’s field study documents an average CBR increase of more than 1,300%, and more than 5,800% in the Southwest region. Treatments use 100% native soils, with no imported material.

5: Subregions studied
>1,300%: Average CBR increase
>5,800%: CBR increase in the Southwest
100%: Native soils, no imported material

Road stabilization at Castions di Strada

An international Midwest reference at Castions di Strada, Italy.

Midwest documents 55 km of stabilized roads. The gallery presents this parent-company reference.

Solar infrastructureUnited States · New Mexico

Solar project stabilization in New Mexico

The project’s fine sands had a CBR of 2. Treatment needed to meet construction specifications.

Using Soil-Sement® Engineered Formula, Midwest raised CBR from 2 to 35. Work covered 17 miles of roads and 16 acres of laydown yards in 21 days. An independent agency verified 100% specification compliance.

2 → 35: CBR before and after treatment
17 miles: Stabilized roads
16 acres: Stabilized laydown yards
21 days: Construction duration
100%: Independently verified compliance

Industrial facilityUnited States

4-year dust control program at an industrial facility

Meeting US EPA requirements on fugitive and respirable dust emissions at a constantly changing industrial site.

Turnkey program started in 2017; several chemistries tested in year one, then EnviroKleen® selected for the following years. Monitored with Visual Emissions Observations and silt-load testing per US EPA methods.

81%: Opacity reduction, year 1
90%: Silt load reduction, year 1
>95%: Silt load vs untreated (years 2-4)
-62%: Pre-season VEO in year 4 vs 2017

Underground mineWestern United States

MineKleen® system at a non-ferrous metal mine

Water application cost over $642,000 per year, required multiple applications per day, and water trucks interfered with daily operations.

Full-site audit, then rollout of the MineKleen® system after a successful test expanded across the operation.

95%: Dust reduction
35%: Cost reduction
73%: Labor reduction
24 / year: Applications reduced to

Gravel runwayNorth Slope, Alaska

Gravel runway stabilization with the SECUR System

A 7-year-old gravel runway void of fines, losing strength during thaw and heavy rainfall, serving Dash Q400, 107 Hercs, C-130 and DC6 aircraft.

Lab testing (particle size distribution, Proctor, CBR), then the SECUR System with EK35® applied for fines preservation and dust control on a new 4" surface course. Installation was completed in one weekend by two round-the-clock crews.

4 inches: Treated depth
1 weekend: Installation window
> minimum requirements: CBR achieved
Eliminated: Water used for dust

Private roadCalifornia vineyard

Eco-Pave® stabilized roads evaluated after 1 year

Stabilize private ranch roads for year-round farm equipment traffic without harming the grapevines and while keeping a natural appearance.

Fall 2018: Eco-Pave® stabilization installed into the upper 4" of native soil with an Eco-Pave® seal coat. Geotechnical assessment with Dynamic Cone Penetrometer testing (ASTM D 6951-03) at 17 locations one year later.

80: CBR stabilized layer (0-4")
25: CBR untreated soil
+200%: Strength gain after 1 year
17: DCP test locations

Major urban projectBoston, Massachusetts

Dust and erosion control at Boston's "Big Dig"

The Central Artery/Tunnel project faced unique dust and erosion compliance challenges with thousands of people, homes and businesses in the construction area.

Midwest's Soil-Sement® Engineered Formula was adopted by the Massachusetts Department of Environmental Protection for both the environmental and economic aspects of dust control.

PM10 / PM2.5: Particles targeted
EPA-verified: Validation
Massachusetts DEP: Adoption
None: Tracking onto public roads
