Aggregate Industries Class 59 No.59002 climbs Whiteball,with the 13:44 Exeter Riverside to Whatley Quarry working,on the 9th of March 2018.
Conveyor bucket system which once linked the Prestonhill Quarry with the River Forth. The quarry - one of two locally - once mined an aggregate used in road surafces, Quartz Dolerite. The quarry has been closed for as long as I can remember, with most of it now underwater. The rusting steel square was a later addition once the structure between the path and the quarry itself was removed, designed to prevent explorers endangering themselves on the structure.

I can't wait to get back for my March workshops in Death Valley!
A growing literature has documented that firm dynamics exhibit substantial differences in developed and developing countries. While there is a massive turnover of firms in developed countries, such a selection mechanism is largely absent in developing countries. Understanding the determinants of firm growth, factor reallocation, and firm-level productivity, as well as the link between firm and industry dynamics is key to shed light on performances of aggregate economies. This conference will have prominent researchers present their recent work on the subject and foster a conversation among scholars that use different approaches to understand firm and industry dynamics and their aggregate implications.
When I was younger, I thought that driveways were only made out of one material one way. It took until I was older to realize that driveway can be made from a number of different types of materials and treated different ways. I like the classic look of a normal concrete. Though there are other treatments that look really nice too.

The former oil wharf at Weaste, long-abandoned, is being redeveloped as an aggregate terminal. The trees have been cleared, the wharf refurbished and other construction is in progress as seen here.
I am told that the operator of the Mersey dredger 'Admiral Day' has acquired a former Harker barge and plans to use it to bring dredged aggregate up the ship canal to this wharf.
Together with the adjacent Premier Cement wharf, this will be a convenient source of construction materials.
Celestite from Ohio, USA.
A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are over 5700 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.
The sulfate minerals all contain one or more sulfate anions (SO4-2).
Celestite (a.k.a. celestine) is a strontium sulfate mineral, SrSO4. Its name has the same etymology as "celestial", meaning "sky", in reference its bluish to pale bluish crystals. This mineral has a nonmetallic luster, a clearish to whitish to pale blue to bluish-gray color, a white streak, a hardness of 3 to 3.5, two cleavages, and is noticeably heavy for its size. It forms diagenetically and also occurs in low-temperature hydrothermal vein systems.
The celestite crystals shown above were partially filling a cavity (vug) in Middle Paleozoic sedimentary rock. The specimen is from northwestern Ohio, which is on the southeastern flanks of the Michigan Basin. The strontium-rich fluids from which the celestite crystallized apparently traveled updip from the Michigan Basin. For more info. on Ohio celestite, see Carlson (1991, Minerals of Ohio, Ohio Geological Survey Bulletin 69, 155 pp.) and Carlson (2015 - Minerals of Ohio, Second Edition, Ohio Geological Survey Bulletin 69 (Second Edition), 290 pp.).

Leadership fixes potholes, not patching.
Chronic neglect of Portland’s streets is manifesting in the burgeoning number and size of dangerously large potholes across the city. Here, pothole road damage is seen in Mount Tabor Park, Portland, Oregon.
Engineering: From a technical perspective, a great deal of information can be gleaned from a deep pothole, as it provides a cross-section-view of the pavement structural section…or lack thereof, as in this case. Here, the asphalt wearing surface is heavily pitted, highly oxidized and brittle, confirming many years of neglect. The asphalt layer is minimal, confirming this road never received the maintenance originally planned. The river-rounded pebbles of the base course layer tell the story of a roadway constructed originally from deficient materials. Roadway base course should be well-graded, faceted aggregate so as to provide optimum particle interlock – a crushed and sieved mix from those same pebbles would suffice. Finally, from the moisture visible in the pothole, and the shape of terrain at the road shoulders, it is clear that poor drainage has contributed to the failure of this road. The conclusion is unequivocal; this road has failed and no amount of patching will restore a level of service – or service life – that should be reasonably expected of it.
